Grain size of metal castingsL TarshisJ Walker
Microstructure, Metal-Mold Reaction and Fluidity of Investment Cast-TiAl Alloys However, the grain size of TiAl alloy castings is gradually reduced with mold preheating temperature due to heterogeneous nucleation near outside of mold ... MG Kim,SY Sung,YJ Kim - 《Materials Transactions》...

The impressive mechanical strength behavior in the BDFe-Mo inferred that an appropriate increase in the concentration of microalloying elements gave rise to the grain refinement of the ferrite and precipitation strengthening of metal carbides. Figure 6 XRF maps of the constituent alloying elements in ...
The structural strength of metallic materials and methods of determination The time is past when "mechanical properties" means ultimate strength, elongation, and impact toughness. It is urgent that we introduce in our investigatio... YR Rauzin,EA Shur - 《Metal Science & Heat Treatment》 被引量...
Excellent soft magnetic properties and appropriate uniaxial magnetic anisotropy field have been achieved in a wide metal volume fraction(x)range for as-deposited(Fe65Co35)x(SiO2)1xgranular films fabricated by magnetron sputtering. With decreasingxfrom 0.86 to 0.53, the coercive force of easy axisHc...
The grain size of the niobium metal milled in the Invicta vibratory mill was about 26 ± 2 nm at a BPR of 5:1, but was only 18 ± 1 at a BPR of 10:1 (Koch, 1993). Similar results were also reported for the pure metal Cu: 25 ± 5 nm for a BPR of 5:1 and 20 ± 1 ...
In general, concentrations of heavy metals tend to increase as the size fractions get finer. However at two sites, near mining areas, the coarser particles show similar or even higher heavy metal concentrations than finer ones. The higher residence time and/or presence of coarser particles from...
Influence of grain size on hot ductility of plain C–Mn steels The influence of grain size on the hot ductility of 0·19 and 0·65wt-%C steels of the CMn type has been determined. For the low-carbon steel, a gram Size ... DN Crowther,B Mintz - 《Metal Science Journal》 被引量:...
The temporal development of heavy metal pollution in sediments from the middle section of the Neckar River was investigated in 56 core profiles. The various interpretations of the data suggest that there has likely been a recent decrease of the hwavy metal load, especially in respect to elements...
